Suitable cross braces are also provided.

Suitable members are provided for supplane.` TheV shaft 12 is jo'urnaled in bearings 19 and v2O which are mounted on suitable supporting members 21 and 22 located at the rear and in front of rv,the carrier member 10. The supports 21- and 221may be secured to the floor 18 inthe usual or any well known`I i thus causing the endless carrier to rotate in manner. 1

The endless carrier is preferably provided with article supporting members. members may be arranged in any lsuitable manner but* preferably vthey are `rotatably mounted on thecarrier 10. As showinthese supporting members are in the forinof shafts'v or spindles 23 and 24. ,Inl order to economi'ze space these shafts may be arranged in staggeredy relation asv clearly shown *in Figure. 2 of the drawing. `The shafts 23 are mounted in journals at'the periphery of the endless carrier 10, while the shafts 24 are. mounted in journals which in turn may be carried by the struts 17 or by any other suitable portion of the carrier inwardlyof the shafts 23.

Vhere the device is to be 'employed for the Apurpose of drying paint on4 automobile wheels these shafts orspindles 23 and 24 may extend laterally beyond the vkfront face of ,thel carrier and areadapted to Ahave .a series" ofy the freshly painted' 'wheels 25 mounted thereon.V lSuitable spacers 26hold the wheels in spaced relation. The vwheels Vare'held on the shafts or spindles by suit.-

able means such 'as the nuts 27 (see'Figure 1).;V v' The endless carrierv 10 is adapted to be rotatedb'y any suitable means 'eithermanually or'by power operated devices. More'- to the shaft 37 (see Fig. 4)

over,"th`eVV spindles or shafts 23 and 24 are adapted to be rotated on vtheir axes' independently of or. in conjunction with the rotation 'of the endless carrier on its axis. The spindles or' shafts 23 and 24 are rotated in order that the protective Huid may not run vor collect onany particular 'part or point on the wheel during the vdrying op`v eration. Y' As shown on the drawing the carrier is rotated'by a Aiiiot'or28 through the mechanism that will now be described. A belt 29 engaging a pulley 35 on the motor 28 operates the pulley 36 which is rigidly secured which 'in turn is journaled in suitable supports 38fand 39 located at the base of the machine. A pulley 41 loosely mounted on the shaft 37 is provided with' one member of a clutch 42 which is adapted to engage the other inember of the clutch 42, carried by the pulley 36. The pulley 41 is adapted to he shifted These Vthus be apparent thatwhen the motor 28 Voperates and the clutch 42 is thrown into operative position the shaft 12 will' rotate k'are so adjusted that sufiicienty time is given 'for vdrying the protective covering on the articles during one rotation ofthe carrier.

Suitable means are provided for causingl a circulation of air aboutthe Vpainted articles Aduring the rotation. ofV the carrier. Preferably the air circulating means is so arranged that the air in circulating forms a continuous circuit. It is understood, however, that this arrangement is 'not necessary to tlie'operation of the device and it is understood that this invention is not limited to such construction.

In order to efficiently accomplish the l,

proper circulation of thel air, av closed passageway isprovided through which air is circulated and within which' the Vmovements of the articles are confined. As shown on the drawings, apassageway 51'r is provided.

This passageway comprises thel front wall 52 which may extend across the front' face of 'the carrier from the top thereof to "the floor v18; an outer wall 53 extending about the carrier; and an inner wall 54 secured in the circular opening 55 formed inthe front wall 52.' The rear wall of the'passageway is formed by a plate 56 rigidly secured to the carrier 10 and is rotatable therewith. It will thus be seen that anannular passageway is provided around which the articles are adapted to travel. y

An air conduit 57v leading from the fan 58 is adapted vto deliver air to the passageway 51. TWhile it is understood that the air may be delivered at any point about the passageway, but for convenience of illustration it is shown on the drawing as ,delivering the air to the top portion of said passageway. Means are provided forreturning tlie air from the lower portionof the passageway tn tlie fan 58. As shown, two conduits 59 and 61 connected with the lowerpoition of the passageway are adapted to deliver the air to the fan 58. l
